Plastic shoe box assembly

ABSTRACT

A plastic shoe box assembly includes a folding body made of a transparent and semi-transparent plastic material, side cover plates, an upper cover plate, and fastening lugs. The folding body is formed with shallow grooves such that the folding body is foldable along the shallow grooves into a U-shaped body, and has front and rear end portions provided with slide grooves. The side cover plates may be inserted into the slide grooves from an upper end of the U-shaped body, and has stop blocks and resilient retaining members engageable with stop grooves and retaining grooves for coupling purposes. The upper cover has front and rear ends connected to the fastening lugs, which has color or number indications. After assembly, projections at the inner edges of the fastening lugs can engage fastening holes in the side covert plates to position the upper cover plate. The shoe box assembly saves storage space prior to assembly, and can be quickly assembled when desired. The indications on the fastening lugs facilitate identification of the contents of the shoe box assembly. Besides, the user can use the shoe box assembly as a protective shoe storage box after purchase, thereby preventing waste of resources.

[0001] (a) Field of the Invention

[0002] The present invention relates to a plastic shoe box assembly, more particularly to a shoe box assembly that aims to reduce storage space and facilitate identification of contents of the shoe box assembly. The plastic shoe box assembly includes a folding body made of a transparent and semi-transparent plastic material, side cover plates, an upper cover plate, and fastening lugs. The folding body is formed with shallow grooves such that the folding body is foldable along the shallow grooves into a U-shaped body, and has front and rear end portions provided with slide grooves. The side cover plates may be inserted into the slide grooves from an upper end of the U-shaped body, and has stop blocks and resilient retaining members engageable with stop grooves and retaining grooves for coupling purposes. The upper cover has front and rear ends connected to the fastening lugs, which has color or number indications. After assembly, projections at the inner edges of the fastening lugs can engage fastening holes in the side covert plates to position the upper cover plate. The shoe box assembly saves storage space prior to assembly, and can be quickly assembled when desired. The indications on the fastening lugs facilitate identification of the contents of the shoe box assembly. Besides, the user can use the shoe box assembly as a protective shoe storage box after purchase, thereby preventing waste of resources.

[0003] (b) Description of the Prior Art

[0004] Conventionally, shoes are packed in boxes made of cardboard paper for temporary storage and protection. Such shoe boxes are stocked in shoe factories for packaging purposes. As the shoe boxes can only be stacked, they require a large amount of storage space. Besides, as the shoe boxes are not transparent, they do not allow easy identification of the model, color and size of the shoes stored therein. Generally, the model, color and size indications are written on the shoe boxes, which is quite unsightly. Furthermore, since paper shoe boxes are not sufficiently rigid and are vulnerable to damage, users tend to throw them away, which is a waste of resources. Even if the shoe boxes are saved for storage boxes, their material do not allow easy identification of the contents thereof.

SUMMARY OF THE INVENTION

[0005] The primary object of the present invention is to provide a plastic shoe box assembly which includes a folding body made of a plastic material, side cover plates, an upper cover plate, and fastening lugs. The folding body is formed with shallow grooves such that the folding body is foldable along the shallow grooves into a U-shaped body, and has front and rear end portions provided with slide grooves. The side cover plates may be inserted into the slide grooves from an upper end of the U-shaped body, and has stop blocks and resilient retaining members engageable with stop grooves and retaining grooves for coupling purposes. The upper cover has front and rear ends connected to the fastening lugs, which has color or number indications. After assembly, projections at the inner edges of the fastening lugs can engage fastening holes in the side covert plates to position the upper cover plate. The shoe box assembly saves storage space prior to assembly, and can be quickly assembled when desired.

[0006] Another object of the present invention is to provide a plastic shoe box assembly which is made of a transparent or semi-transparent plastic material and which includes fastening lugs with color or number indications to facilitate identification of the model, color and size of the shoes contained in the shoe box assembly.

[0007] A further object of the present invention is to provide a plastic shoe box assembly which has sufficient rigidity to withstand pressure and which is not vulnerable to damage so that the user can use the shoe box assembly as a protective storage box, thereby preventing waste of resources.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0014] With reference to the drawings, the present invention is shown to include a folding body 1, side cover plates 2, an upper cover plate 3, and fastening lugs 4. The present invention as a whole is made of transparent or semi-transparent plastic material. The folding body 1 is provided with shallow grooves 10 such that it can be folded into a U-shaped member, and has front and rear end portions provided with slide grooves 11, which have end portions formed with stop grooves 12 and retaining holes 13. The periphery of each side cover plate 2 is formed with a projecting track 20 engageable with the slide groove 11. The upper end of the track 20 is provided with a stop block 21 and a resilient retaining member 22 corresponding to the respective stop groove 12 and retaining hole 13. The upper cover plate 3 has front and rear ends provided with connecting holes 30 for pivotal engagement with the fastening lugs 4. The inner edge of each fastening lug 4 is formed with a projection 40. Each side cover plate 2 is provided with a fastening hole 23 corresponding to the projection 40 of the respective fastening lug 4 so that they are inter-engageable.

[0015] In actual use, the shoe box of this invention can be stocked in factory in a flat state so as to reduce storage space, and can be quickly assembled into a box shape during manufacture of the shoes. Firstly, the folding body 1 is folded along the shallow grooves 10 on both sides into a U-shape. Then, the tracks of the side cover plates 2 are inserted into the slide grooves in the front and rear ends to the bottommost end such that the stop blocks 21 and the retaining member 22 project into the stop grooves 12 and retaining holes 13 in the slide grooves 11, respectively, in a firm manner. In addition, according to the color and size of the shoes, fastening lugs 4 with corresponding color or number indications can be connected pivotally to the connecting holes 30 of the upper cover plate 3, and the upper cover plate 3 can engage the fastening holes 23 in the side cover plates 2 by means of the projections 40 at the inner edge of the fastening lugs 4 to thereby enable the upper cover plate 3 to be removable. As such, the shoe box of this invention can be quickly assembled without using any tool. Since the shoe box of this invention is made of a transparent or semi-transparent plastic material, matched by fastening lugs 4 with color or number indications, the model, color and size of the shoes stored inside the shoe box can be easily identified when looking for shoes to meet customers' requirements. Shoe boxes of this invention can be neatly stored. In addition, after purchase of the shoes, the user can use the shoe box to store the shoes without the need to buy additional shoe storing box, since it is made of plastic that can withstand pressure and wetness and can protective the shoes stored therein. As such, there is no waste of resources. Besides, the user can quickly identify the shoes in the shoe box.
